This is a quick update on my earlier post where I have included orbBasic code for the Orbotix Sphero which will give it some rudimentary autonomy. Observe that the code comments below should not be sent to the Sphero. I am currently working on creating a more user friendly tool for loading basic into the sphero. The undocumented command line tool included in the embryonic framework from my previous post will read an orbBasic file, strip the comments, and transfer it to the Sphero. However, since I only posted source code you will need Visual Studio to compile and run it.
